我在对齐环境中输入了一些方程式,我想在它们下面写一些东西。但同时也希望它们对齐。特别是想象一下我想要或者我可以这样做
\begin{align}
\mathrm{E_{0}\sum_{t=0}^{\infty}} & \beta^t U(c_{it}) \;\; \\
c_{it} + d_{it+1} + x_{it} & = y_{it} - w_tl_{it} + (1+r_t)d_{it} \\
\text{The budget constraint & of the entrepreneur} \nonumber \\
y_{it} & = f(k_{it}, l_{it}, z_{it}) \\
\text{The technology that & the entrepreneur operates} \nonumber \\
k_{it+1} & = x_{it} - (1-\delta)k_{it} \\
\text{the linear technology &that transforms final goods to investment goods} \nonumber\\
d_{it} & \leq \theta k_{it} \\
\text{collateral & constraint} \nonumber \\
z_{it} & \sim \text{exogenous random process drawn from} \;\; \psi(z)
\end{align}
当然,LaTeX 会给出错误,因为我在 \text{} 里面有 &。有人能提出一个 LaTeX 可以产生的替代方案吗?
答案1
您确定使用\intertext
(或\shortintertext
) 命令不是更好的选择吗?我看不出您的文本中需要对齐什么。无论如何,这是我的建议:
\documentclass{article}
\usepackage{mathtools}
\begin{document}
\begin{align}
\mathrm{E_{0}\sum_{t=0}^{\infty}} & \beta^t U(c_{it}) \;\; \\
c_{it} + d_{it+1} + x_{it} & = y_{it} - w_tl_{it} + (1+r_t)d_{it} \\
\intertext{The budget constraint of the entrepreneur}
y_{it} & = f(k_{it}, l_{it}, z_{it}) \\
\intertext{The technology that the entrepreneur operates}
k_{it+1} & = x_{it} - (1-\delta)k_{it} \\
\intertext{the linear technology that transforms final goods to investment goods}
d_{it} & \leq \theta k_{it} \\
\intertext{collateral constraint}
z_{it} & \sim \text{exogenous random process drawn from} \;\;\psi(z)
\end{align}
\end{document}
和\shortintertext
:
答案2
该\intertext
命令就是您想要的。您可以将方程式保持在=
或~
符号处对齐,而文本则位于它们之间。以下是 MWE 来说明\intertext
命令的用法:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
1 &=2\\
\intertext{aaa}
a+b&=c+d\\
\intertext{dont't forget that \begin{equation}1=1\end{equation}}
0.5&=\frac{1}{2}
\end{align}
\end{document}
输出为:
如果您也需要将文本居中,只需将其放在\centering
括号内即可\intertext{\centering .....}
。
答案3
解决这个问题的一种方法是\text
在 之前结束命令&
并在 之后开始一个新命令&
。
为了使空格正确,请在新内容开头加\text{}
一个空格。即\text{ text}
。您的代码(使用测试pdflatex
)将如下所示:
\begin{align}
\mathrm{E_{0}\sum_{t=0}^{\infty}} & \beta^t U(c_{it}) \;\; \\
c_{it} + d_{it+1} + x_{it} & = y_{it} - w_tl_{it} + (1+r_t)d_{it} \\
\text{The budget constraint} &\text{ of the entrepreneur} \nonumber \\
y_{it} & = f(k_{it}, l_{it}, z_{it}) \\
\text{The technology that} &\text{ the entrepreneur operates} \nonumber \\
k_{it+1} & = x_{it} - (1-\delta)k_{it} \\
\text{the linear technology} &\text{ that transforms final goods to investment goods} \nonumber\\
d_{it} & \leq \theta k_{it} \\
\text{collateral} &\text{ constraint} \nonumber \\
z_{it} & \sim \text{exogenous random process drawn from} \;\; \psi(z)
\end{align}
